" 1 Claim, (o1. 229-52 My invention relates to improvements in "fold shows a plan of the box before folding and Fig- 10' ures 2 and 3 show, plan and end view respectively of the box shown in Figure l when folded. Simihandles, the parts k may be folded fiat against lar letters refer to similar parts throughout. The box, shown in Fig. 1 before folding,consists of asingle piece of cardboard or othersuitable l5 material cut so as to form with its central per-' tion the bottom a and four sides b, 0,12 and c; it has two projecting parts g and 7' on opposite sides, which fold over the top of the box so as to form the top surface; each of these projecting parts 20 has a further projection shaped so as to consist of a handle-piece k and a locking flap 1, formed by cutting the slot m; the box also has on the remaining two sides projections f and. it intended to fold over the projections g and and eachhav ing a slot nl shaped so as to fit over the two handles it and the locking flaps Zin orderthat when the box is assembled the flaps Z will be po-Y sitioned so as to be engaged by the back of the fingers or thumb and thus be pressed down- The dotted. lines in Fig. 1 indicate the lines of folding, which may with some weightsof material requireto'be cut slightly on the surface soas to enable folding to be done accurately and easily. 35

e are folded into position, the corner parts 0 being folded inwardly. The projections g and :i are next folded over so that they meet and form togather the top surface of the box, the parts It and. I being folded in such a way that they stand up-;

wardly against the adjacent slotted projection.

, In assembling the box the four sides 12, c, d, and

seenthat by reason of-this novel arrangement of parts that when the box orcontainer is in its I assembled position, the upper flap Zwillbe pressed downwardly by the fingers or thumb and thus insure the parts being maintained .firmly in 5,

position. I attain these objects in the mannerillustrated in the accompanying drawing in which Figure 1 The locking flaps may be folded in opposite directions or in the same direction and may be fastened down if thought necessary, although they should hold satisfactorily without fastening. 10

It. will be obviousthat, when not required, as

thetopsurface of the box.

.It'ishould be pointed out that the weight of material used and theshape of the box can be varied greatly according to the purpose for which it is intended. It might be that in some uses of the box itmight be found desirable to re-inforce the parts 9,7 and k or the parts 9, 7', k and l in order to provide additional strength in connection with v the handles.

I claim: a I y A foldable box formed from a blank and having a polygonal intermediate central portion constituting the bottom, opposed pairs of projections extending from the bottom, said projections when folded arranged to form thesides of the box, adj aa cent projections-being connected by corner portions which when folded inwardly along diagonal lines assume a position parallel with the sides of the box, one pair of opposed projections having extensions which when folded, constitute the top of the box, said extensions terminating in handle portions arranged to extend upwardly from the top in adjacent relation and having formed therein locking flaps, the other pair of projections having slotted extensions arranged to pass over the T handles and overlap the top, said locking flaps when the box is assembled arranged to be bent laterally'in the same direction to engage the uppermost one of theprojections having the slotted extensions, whereby when the, handles are gripped by the hand, thethumb or fingers will engage one a of the locking flaps to press the flaps against the slotted extension, and thus insure the parts being maintained positively in their folded positions.
